STRAP SUPPORT FOR GUNS.

APILlCATION FILED SEPT.12, 1912,

T all whom it may concern:

Be. itknown that I. OTTO Paoonzvow, a citizen of the United States,residing at Vlest Allis, county of Milwaukee. and State of Wisconsin,have invented new and useful Improvements in Strap-Supports for Guns, ofwhich the following is a specification.

Myinvention relates to improvements in strap fsupports for guns, withespecial reference to that class of strap supports shown and describedin my former application for Letters Patent of the United States, SerialI tiled March 11th, 1912, and allowed July 22, 1912.

The object of my present invention is to proyide means for locking thewindinc spool with the strap extended to any esired length. I

Incidentally to the above object, I also provide means whereby the spoolmay be manually actuated and the spring illustrated in my former patentdispensed with.

Inthe,drawingsFigure 1 is a side view of a gun embodying my invention.Fig. 2 is a sectional view of the Winding spool and casing, removed fromthe gun stock, and

showing also a portion of the strap partially wound thereon. 3 is a sideview. partly in section, of a winding spool and casing embodying amodified form of my invention, in which a. winding spring is employed.Fig. 4 is a sectional view otthe same, drawn t a. plane exposing thewinding shaft.

Like parts are identified by the same reference characters throughoutthe several views.

The gun stock 1 has a cylindrical casing 2 socketed therein similar tothat shown and-- described in my former application? A-wind ing shaft 3extends through the casing trans versely and carries a spool 4 uponwhich the gun supporting strap 5 is adapted to be wound. said strapextending through a pcripheral opening 0 in the casing, substan tiallyas shownand described in my former application. in the constructionillustrated in Figs. 1 and 2. the projecting end (3 of the shaft isflattened and adapted to receive the head 7 of a crank arm 8. The crankarm 8 is formed in sections connected with each other by a hinged jointat 10, and the outer section of the arm is provided with a locking pin11. preferably rigidly secured to the arm and adapted to engage in holes12- formed in the casing-flange 13. When the pin 11 is r snaresSTRAP-SUPPORT reasons.

Specification of Letters Patent.

Patented Nov. 3, o

Application filed September 12, 1912. Serial No. 719,905.

inserted in one of these holes 12, the crank arm 8 is. locked against,rotation and is also held closelytothe adjacent wall of the casing 2.pin 11 is adapted to fit snugly in theholes 1:2 and to bind therein byfrictional contact. The hinge-l0 is alsofpreferably formed with atight-fitting pintle,

whereby an accidental swinging of onesection upon the other-isprevented. By manually pulling upon the pin 11, however, said pin may bewithdrawn from the hole 12 in which it is engaged, and the outersectionsimultaneously swung to a position at right angles to the inner section,whereupon said outer section may serve as a crank handle to facilitaterei olving the shaft. 6 and winding spool 4 When the strap is extendedor rewound uponthe spoolto the desired extent, the outer section of thecrank arm 8 will be swung into alinemcnt with the inner section, asillustrated in Fig- 2. and the pin 11 reengaged in one of the holes 12.The outer end of the strap being provided with a fastening 15 engagingan eye-piece 16011 the gun barrel, it is obviousthat when the strap theshoulder from irritating pressure, such as'would be exerted by the gunbarrel if the strappere not used. It is ob ious that the strap may beerrtrndedflto desired ektent from the adjustment illustrated by fulllines in Fig. 1 to facilitate carrying the gun by suspending it from theshoulder, or from a wall support, or any other desired point.

By employing a jointed crank arm 8, l am enabled to use a thin andcomparatively wide arm, which will lie substantially flat against. theexposed wall of the casing, the pin 11 being provided with a broad fiathead, which projects but little from said wall. The arm, therefore. willnot catch in the clothing of the user, or otl'ierwise interfere with theordinary use of the gun. This arrangement, however, makes it highlydesirable that the arm 8 should be jointed in order that the outersection may be swung ioo outwardly to facilitate rotating the crank andalso to Withdraw thepin 11 from the casing holes 12. f

Referring to Figs. 3 and *4, it will beobserved that a strap Windingspool 18 is em-p ployeihand this spool is provided at one end .withpanend disk 19, provided with a series of notches 20. A shaft 21 isemployed simi-, lar to the shaft 3, and a casing 22 inclo'ses the spooland is provided with ya sepa. ratecompartment 24-, snnllar to thatshown: in my former application, and in which a ivindin s rin 25 'islocated, the ends n P g of said spring being connected, 'with the shaftand easing respectively. A segmen-' tal locking member 26 is pivoted at27 to the front Wall of the casin and is provided tract locking a'r1n26and withdraw lip 28 adjustment "is reached,

Wardly against the tension of the from the notch 20 in which itisengaged. As soon as the lockmgarn s retracted, the

s rin 25 will be eflective'to vvind u the strap, but if itis desired toextend the strap,

this can be done :by pulling the same outwinding position of strapprojection" 31 may be released, whereupon lip 28 willautoi'uat ical'ly,reengage with oneof the notches 20 and lock the spool against rotation.

'Itwill be understood that'if desired, the crank arm 8 shown in Figs. 1and 2 may be applied to the shaft used for unwinding spring. I When thedesired the spring or'for looking the spool. \Vherethis is done, thelock-, ingi arm 26 may be dispensed with; in this i I I 210 f Figs. 3and 4, and

eonstruction aswell as in the construction shown in Figs. 1 and 2. Wherethe gun stock is thick enough so that a socket may be provided thereinof suflicient depth to readily receive the casing 22, the construction.SllOWll in Figs. 8 and -1- Will preferably be employed, for the reasonthat thesurtaoe of the casing will have no projecting parts eX- cept theslight projection of the member 31, but where the gun stock is thin anda deep easing cannotbe readily employedfthe'jonsti-uetion shown in Figs.1 and 2 willbe preferred. The additional easing depth re.-

quired for the reception of the spring 25 is not required for theconstructionshoivn in Figs, 1 and'2.'
